how to know the result of serial loopback test by using PRBS?

Hi All, 

I am using Stratix IV GT device. I have done some configuration to connect my switch to PMA of the GT device. 

However, firstly, I want to check if my configuration is correct or not, so that I did serial loopback test with PRBS 7 mode and run compile and synthesis. 

But I don't know what next step is to check the result of this test. 

If you have some experience, could you help me on this issue? 

 

Thank you very much.

The Transceiver Toolkit provides a good interface for the kind of testing you're looking for. It lets you put in different PRBS patterns and check bit error rates. It also lets you change transceiver settings. 

 

Download the appropriate example project and modify for your setup.

I've only debugged my transceivers in depth using the toolkit so I'm not sure if there are other ways. The Qsys projects in the examples have the pattern generators and checkers so it makes it pretty easy to test.

Hi All, 

 

Thank you very much for sharing your experience. 

I can check the result by monitoring pass/fail output ports.
